    To find out what Transmission you have, Go to the inside of your Glove and you will see a White Sticker.....with your Trucks Vin # and a Series of Letter's and Number's.....those are RPO Code's, in short what your Truck came with from the Factory,

    You will be looking for one of the Following RPO Code's,
    .....M30.........which is the 4 Speed Auto.....4L60e
    .....MYC........which is the 6 Speed Auto.....
    .6L80

    Edit:.....Forgot about the 3rd Transmission...RPO Code...
    ..MYD......which is the 6 Speed Auto......6L90.
